RANGE BOILER STAND.

Specification of Letters Patent- Patented Jan. 12, 1909.

Application filed. August 28, 1908. Serial No. 450,647;

citizen of the United States, residing at St.-

Louis, State of Missouri, have invented certain new and usefulImprovements in Range- Boiler Stands, of which'the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

My invention has relation to improvements in boiler-stands; and it.consists in the novel construction of stand more fully set forth in thespecification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the stand; FigrQ is anend elevation thereof; Fig. 3 is a horizontal section on the line 33 ofFig. 1; Fig. 4 is an enlarged vertical longitudinal section on line 4-4of Fig. 3, the bases of the standards being shown in side elevation;Fig. 5 is a vertical cross-section on the line 55 of Fig. 4; Fig. 6 is atop plan of one of the supportingstandards; and Fig. 7 is a perspectiveof the lower end of the supporting standard.

The object of my invention is to construct a range-boiler. stand whichshall occupy a limited amount of floor space; one which can be readilyassembled andtaken apart; one capable of ready adjustment for varioussizes or diameters of boilers; one which can be assembled without theuse of bolts, rivets, or similar fastening devices; one which can becheaply manufactured, contain a .minimum number of parts, and onepossessing further and other advantages better apparent from a detaileddescription of the invention which is as follows:

Referring to the drawings. B, represents a suitable oblong base orcasting provided with terminal legs L. and side legs L. the latterinclining so' as to br ng the several legs within the limits of a.common circumscribing circle, such circle representing the maximum fl orspace taken up by the supporting base of the stand. Formed along themiddle of the upper edges of the sides of the oblong base B aredepressions d, on either side of which are formed, a series of shallowgrooi as or depressions l. 1. On the lower edges of the side walls ofthe base, immediately below the central depression. d and extending topoints oppo ite the first. of the series of rooves l on-either side ofsaid epression d are a series of V-shaped notches 2, 2, the spacesbetween he notches and end.

. Walls of the oblong base beingoccupied by suitably spaced lugs orprojections b, 3, the terminal'lugs 3- being-preferably formedwedge-shaped as shown by. reason of their close proximity to said endWalls.

The standards 4 by which the range-boiler R is directly supported, arecast in the shape substantially as shown in the'drawings, the upper endsof the standards being formed with laterally projecting arms 5 having fledges a engaging the raised bottom of "the boiler, and terminating'infingers b which engage the base of the peripheral walls of the boiler.Each standard 4 terminates at the bottom in a locking leg or projection(3 of wedge-formation, the sides of the wedge nions 7 which are adaptedto rest in a pair of oppositely disposed recesses 1, 1; the ase of theinner face of the wedge term nates in lugs or extensionsS, 8, whichengage a pair of oppositely disposed V-shaped notches-2; and the loweredge of the outer face of the wedge terminates in extensions or lugs 9,9, which are adapted to engage an adjacent pair of lugs 3, 3, and thusprevent accidental displacement of' a standard when once looked in placeon the base B. The sidesof the le 6 are cut away or removed a depthindicated by the offset or shoulder a in order to allow for the presenceof the middle lug 3, which naturally will occupy the space thus providedfor it when the standard is shifted to rest in the outermost pair ofgrooves 1, 1, in which case the-extensions 9, 9, will engage theterminal lugs 3, 3. In order "tolock the standard in position, the sameis turned slightly to allow the leg 6 to pass freely between-thesidewalls of the base whereupon it is turned so as to bring l 7 thetrleuuions 7, into their corresponding pair of depressions 1, 1, theextensions 8, 8, 1 being made to engage their corresponding pair-ofrecesses 2. 2. To prevent accidental displacement of the standard by aninward tilting thereof, the extensions 9 will strike their adjacent'lugs3 (3) (Fig. 4) and thus arrest an undue-movement in this direction. Itwill be seen that each standard is inclined not only to the verticalplane of-the middle longitudinal axis of the base B, but to thecorrespondingvertical plane of the transverse axis, so that when thepairof standards are in place, the terminal'fingers b, b, will be disposedon the perimeter o'f-the same circle (representing in F ig. 6, the outercurve of terminatingat the top on each side in trim-- the boiler), thuspermitting the several fingers b (tour in number) to simultaneouslyengage the outer wall of the boiler supported betweeiithem. \Vhether thestandards occu-py positions represented by the middle grooves 1, 1, orthe inner or outer grooves (dotted positions Fig.1), the fingers b willalways fall on the are of the circle representing the cross section ofthe boiler; Of course, for a small circle, a greater portion of such'circle will be engaged by the fingers than would be the case for a large4, 4, converging as they -be readily packed for shipment.-

Having described my invention, what I- claim is- I 1. In combinationwith a bar a, a pair of standards detachably looked thereto on each sideof the center thereof, and inclined to vertical planes disposed alonintersecting axes of the base, said standar s terminating at the topwith parallel disposed arms, substantially asset forth.

2. In combination with an oblong base:

provided with series of upper depressions on the sides thereof, and withnotches at the lower edges of said sides and having lugs disposed on theinner faces of the sides contiguous to the notches, a pair of standardshaving locking legs provided with upper terminaltrunnions for engagingthe depres sions, inner basal lateral extensions for engaging a pair ofoppositely disposed notches,

and-having outer basal extensions for engaging' the lugs to preventaccidental displacement of the standards, the latter being inclined fromo)posi'te directions to the' vere tical planes 0 the middle longitudinaland transverse axes of the base, and provided with upper laterallprojecting parallel 3. In combination with an open base, provided withopposing wallshaving upper. de-

pressions and bottom notches, a pair of standards having basal lockinglegs, and means on .the legs for simultaneously engaging said depressons and notches, sub--c staiitially as set forth.

4-. In combination with an open oblong base provided on its side wallswith upper depressions and bottom notches, a pair of standardshaving'basal legs, and lateral trunnions and extensions respectivelyengaging the depressions and notches aforesaid, and-means on the sidewalls of the base and on the legs for preventing accidental displacementof the legs when once engaged,

substantially as set forth.

'5. In combination with an oblong base having its side walls providedwith upper depressions and bottom notches, a epairrof standards inclinedto the vertical planes of the longitudinal and transverse axes of thebase, terminal legs on the standards having lateral trunnions and basalextensions for engaging the depressions and notches aforesaid, lugsdisposed on the inner faces of the side walls contiguous to the notches,and an 7 additional pair of extensions formed with the legs for engagingthe lugs to prevent undue tiltingand dis lacement of the standards whenonce .in ocked position on the base, the upper ends 'ofthe standardsbeing provided with arms extending in parallel relation but in oppositedirections and terminating in fingers, substantially as set forth.

6.' In a stand, a pair of standards inclined toward a common axis fromopposite direct-ions, and terminating in parallel arms extendin v inopposite directions toward a vertical p ane passing through said axis,said arms having upwardly projecting fingers at opposite ends thereofdisposed on the perimeter of a common circle, substantially set forth. aV

7. In combination with a base composed of an open frame, a pair ofstandards, legs at the ends of the standards, and means on the base andlegs respectively for securing the latter to the base at differentdistances from the center of said base, substantially as set forth.

8. In combination with a base'coinposed of an oblong frame, a pair ofstandards, legs foiining the lower terminals of the standards anddisposed in the general plane of thebase and legs respectively forlocking the latter to the former at different distances from thetransverse center of the base,
